Crimson Steam Pirates

Crimson Steam Pirates is a 2011 video game for iOS. It was created by Harebrained Schemes, Jordan Weisman's current development studio, published by Bungie, creators of the Halo franchise. It is a turn-based strategy game in which the player commands an army of steam-powered ships, submarines, and airplanes in order to assault enemy fleets and bases. While not explicitly related to the two Crimson Skies games, it shares many similarities, and could conceivably take place within the same universe, sixty or seventy years earlier.
